Heat is conducted through a material with a temperature gradient of – 9000 K/m. The conductivity of the material is 25 W/m-K. If this heat is transferred to surroundings at 30°C with a convection coefficient of 345 W/m2 -K, determine the surface temperature, if the heat is radiated to the surroundings at 30°C determine the surface temperature.

2.38 The addition of aluminum fins has been suggested to increase the rate of heat dissipation from one side of an electronic device 1 m wide and 1 m tall. The fins are to be rectangular in cross section, 2.5 cm long and 0.25 cm thick, as shown in the figure. There are to be 100 fins per meter. The convection heat transfer coefficient, both for the wall and the fins, is estimated to be K. With this information determine the percent increase in the rate of heat transfer of the finned wall compared to the bare wall.
